TECHNICAL FIELD

The embodiments herein relate to an agricultural sprayer unit and aspray deflecting mechanism for an agricultural sprayer unit, whichdeflects and re-directs unutilized dispensed fluid from sprayer nozzlesto a sprayer fluid tank of the agricultural sprayer unit.

BACKGROUND

Agricultural sprayer is used to spray any of chemical agent andbiological agent to the crops cultivated in a region to treat thedisease in crops or to provide nutrition to the crops. A conventionalagricultural sprayer mainly comprises a tank which is used to store anyof chemical agent and biological agent, a plurality of nozzles which areused to spray the chemical/biological agent to crops, and a mechanicalpump which is usually driven by a power take-off shaft (PTO shaft) of avehicle to pump any of chemical agent and biological agent from the tankto the plurality of nozzles. Each nozzle of the conventionalagricultural sprayer unit is used to spray any of chemical agent andbiological agent in directions irrespective of the plants to be treatedwhich in turn would overload other healthy plants with chemical agentswhich is undesirable and also results in wastage of chemicalagent/biological agent, increased cost for refilling chemicalagent/biological agent in tank and also results in contamination ofwater, soil and air which is undesirable.
